I have a command which creates waves ontop of a background image:
ffmpeg -y -i "Assets/Screens/new.png" -i "Temp/video.mp4" -i "Temp/audio.mp3" -filter_complex "[2:a]showwaves=mode=cline:s=255x81:scale=sqrt:colors=0x222222,colorkey=0x000000:0.01:0.1,format=yuva420p[w];[v][w]overlay=240:594,scale=1920:1080[outv]" -map "[outv]" -map 2:a -movflags +faststart -c:v libx264 -c:a aac -preset veryfast -shortest "output.mp4"
How can I also overlay a 1024x576px video at position 756:252?
I have already included the video file as the second (1:v) input, but I can't seem to get the filters to play nicely.
Thanks for any help.
Overlay the image with the video, and feed the overlay-ed output to your existing filter.
The part [1:v][0:v]overlay=756:252[t] overlays video.mp4 and new.png into intermediate video stream [t].
[t][w]overlay=240:594 replaces your [v][w]overlay=240:594.
Complete command:
ffmpeg -y -i "Assets/Screens/new.png" -i "Temp/video.mp4" -i "Temp/audio.mp3" -filter_complex "[1:v][0:v]overlay=756:252[t];[2:a]showwaves=mode=cline:s=255x81:scale=sqrt:colors=0x222222,colorkey=0x000000:0.01:0.1,format=yuva420p[w];[t][w]overlay=240:594,scale=1920:1080[outv]" -map "[outv]" -map 2:a -movflags +faststart -c:v libx264 -c:a aac -preset veryfast -shortest "output.mp4"
I hope I got it right, testing is difficult without having the inputs...

I have a problem with an ffmpeg command.
I want to add the same sound several times in the final video and then add a watermark above.
When I do the full command, it doesn't work correctly because the sound is only played once (the first reference):
ffmpeg -i "assets/frame%05d.png" -i "assets/sound.mp3" -loop 1 -i
"assets/watermark.png" -filter_complex
"[1:a]adelay=1000|1000[s1];[1:a]adelay=3000|3000[s2];[s1][s2]amix=2[a];[0:v][2:v]overlay=shortest=1[outv]"
-map "[outv]" -map "[a]" -c:v libx264 -pix_fmt yuv420p -preset ultrafast -y "result.mp4"
When I don't add the watermark, it works correctly:
ffmpeg -i "assets/frame%05d.png" -i "assets/sound.mp3" -filter_complex
"[1:a]adelay=1000|1000[s1];[1:a]adelay=3000|3000[s2];[s1][s2]amix=2[a]"
-map 0:v -map "[a]" -c:v libx264 -pix_fmt yuv420p -preset ultrafast -y "result.mp4"
Try this:
ffmpeg -i "assets/frame%05d.png" \
-stream_loop -1 -i "assets/sound.mp3" \
-loop 1 -i "assets/watermark.png" \
-filter_complex "[1:a]adelay=1000|1000[s1];\
[1:a]adelay=3000|3000[s2];\
[s1][s2]amix=2[a];\
[0:v][2:v]overlay=shortest=1[outv]" \
-map "[outv]" -map "[a]" -shortest \
-c:v libx264 -pix_fmt yuv420p -preset ultrafast -y "result.mp4"
-stream_loop -1 input option loops the input infinitely and -shortest output option stops the audio when video is done.
p.s., I think an aecho filter can combine the 2nd adelay and amix filters.
I found the problem was that the different frames that make up the video were not all correctly encoded which caused the problem with the sounds.
ffmpeg can't read indexed PNG correctly.
You must therefore use this option (for those like me who use imagick):
$imagick->setOption('png:color-type', 6);
$imagick->writeImage('frame00000.png');
MY CODE
-i "A.mov" -i "B.mp4" -filter_complex "[1:v]setpts=PTS+5/TB[a];[1:v][a]overlay=enable=gte(t\,5):eof_action=pass,format=yuv420p[out]" -map "[out]" -map 0:a? -c:v libx264 -crf 18 -c:a copy "f.mov" -y
This will overlay B.mp4 in font of A.mov but I need B.mp4 As blackground
Thank You.
I'm very new to ffmpeg but so far I'm enjoying it. But I'm stuck on something. I want to combine these two commands into one, something I'm sure must be possible, but after countless hours and no luck, here I am :)
ffmpeg -y -f concat -safe 0 -protocol_whitelist "file,http,https,tcp,tls" -i "tmp.images.txt" -i "tmp.audio.mp3" -filter_complex "drawbox=y=ih-38:color=black#0.6:width=iw:height=38:t=fill, drawtext=fontfile=Assets/calibrib.ttf:text='%%~ni':fontcolor=white:fontsize=14:x=(w-tw)/2:y=(h)-24" -c:v libx264 -preset veryfast -tune stillimage -shortest -pix_fmt yuv420p "tmp.slide.mp4"
ffmpeg -loop 1 -framerate 2 -i "Assets/studio.jpg" -i tmp.slide.mp4 -filter_complex "[1]scale=879:496[inner];[0][inner]overlay=207:49:shortest=1[out]" -map "[out]" -map 1:a -c:a aac -y tmp.output.mp4
the first line creates a slideshow and places text at bottom
the second line takes the slideshow video and inserts it into a background image before outputting final video
Use
ffmpeg -y -f concat -safe 0 -protocol_whitelist "file,http,https,tcp,tls" -i "tmp.images.txt" -i "tmp.audio.mp3" -i "Assets/studio.jpg" -filter_complex "[0]drawbox=y=ih-38:color=black#0.6:width=iw:height=38:t=fill, drawtext=fontfile=Assets/calibrib.ttf:text='%%~ni':fontcolor=white:fontsize=14:x=(w-tw)/2:y=(h)-24,scale=879:496[inner];[2][inner]overlay=207:49" -c:v libx264 -preset veryfast -tune stillimage -c:a aac -shortest -pix_fmt yuv420p "tmp.slide.mp4"
I am attempting to have multiple output files in ffmpeg map to multiple inputs however instead of each input mapping to a unique output I get the first input mapping to the first video and then the next videos never get created at all, I will describe exactly what I am trying to achieve below,
I need to:
create multiple video output files
from multiple audio input files
which all use the same one common image file to create the
video
I will post my command below, any help would be greatly appreciated thanks
-y -i input1.mp3 -i input2.mp3 -f image2 -loop 1 -r 2 -i imagefile.png -shortest -c:a aac -c:v mpeg4 -crf 18 -preset veryfast -movflags faststart -map 0 output1.mp4 -map1 output2.mp4
Basic command
ffmpeg -i input1.mp3 -i input2.mp3 -loop 1 -framerate 10 -i imagefile.png -map 2:v -map 0:a -vf format=yuv420p -shortest output1.mp4 -map 2:v -map 1:a -vf format=yuv420p -shortest output2.mp4
The video is filtered and encoded once per output.
With the split filter
ffmpeg -i input1.mp3 -i input2.mp3 -loop 1 -framerate 10 -i imagefile.png -filter_complex "[2:v]format=yuv420p,split=outputs=2[v0][v1]" -map "[v0] -map 0:a -shortest -movflags +faststart output1.mp4 -map "[v1]" -map 1:a -shortest -movflags +faststart output2.mp4
The video is filtered once total, and encoded separately for each output.
Pipe
ffmpeg -y -v error -loop 1 -framerate 10 -i imagefile.png -filter_complex "[0:v]format=yuv420p[v]" -map "[v]" -c:v libx264 -f nut - | ffmpeg -y -i - -i input1.mp3 -i input2.mp3 -map 0:v -map 1:a -c:v copy -shortest -movflags +faststart output1.mp4 -map 0:v -map 2:a -c:v copy -shortest -movflags +faststart output2.mp4
The video is filtered and encoded only once and each output stream copies it.
I'm playing with ffmpeg to generate a pretty video out of an mp3 + jpg.
I've managed to generate a video that takes a jpg as a background, and adds a waveform complex filter on top of it (and removes the black bg as an overlay).
This works:
ffmpeg -y -i 1.mp3 -loop 1 -i 1.jpg -filter_complex "[0:a]showwaves=s=1280x720:mode=cline,colorkey=0x000000:0.01:0.1,format=yuva420p[v];[1:v][v]overlay[outv]" -map "[outv]" -pix_fmt yuv420p -map 0:a -c:v libx264 -c:a copy -shortest output.mp4
I've been trying to add text somewhere in the generated video too. I'm trying the drawtext filter. I can't get this to work however, so it seems I don't understand the syntax, or how to combine filters.
This doesn't work:
ffmpeg -y -i 1.mp3 -loop 1 -i 1.jpg -filter_complex "[0:a]showwaves=s=1280x720:mode=line,colorkey=0x000000:0.01:0.1,format=yuva420p[v];[1:v][v]overlay[outv]" -filter_complex "[v]drawtext=text='My custom text test':fontcolor=White#0.5: fontsize=30:font=Arvo:x=(w-text_w)/5:y=(h-text_h)/5[out]" -map "[outv]" -pix_fmt yuv420p -map 0:a -c:v libx264 -c:a copy -shortest output.mp4
Would love some pointers!
Filteres operating in series should be chained together
ffmpeg -y -i 1.mp3 -loop 1 -i 1.jpg \
-filter_complex "[0:a]showwaves=s=1280x720:mode=line,colorkey=0x000000:0.01:0.1,
format=yuva420p[v];
[1:v][v]overlay,
drawtext=text='My custom text test':fontcolor=White#0.5:
fontsize=30:font=Arvo:x=(w-text_w)/5:y=(h-text_h)/5[outv]"
-map "[outv]" -pix_fmt yuv420p -map 0:a -c:v libx264 -c:a copy -shortest output.mp4
(You applied the drawtext onto the output of showwaves; it can be directly applied on the overlay output)
